Lifetimes of Confined Acoustic Phonons in Ultra-Thin Silicon Membranes

John Cuffe, Emigdio Chávez, Pierre-Olivier Chapuis, Francesc Alzina, Oliver Ristow, Andrey Shchepetov, Mike Hettich, Thomas Dekorsy, Clivia M. Sotomayor Torres, Mika Prunnila, Jouni Ahopelto

We study the relaxation of coherent acoustic phonon modes with frequencies up to 500 GHz in ultra-thin free-standing silicon membranes. Using an ultrafast pump-probe technique of asynchronous optical sampling, we observe that the decay time of the first-order dilatational mode decreases...

Ultrafast optical technique for measuring the electrical dependence of the elasticity of piezoelectric thin film : demonstration on AlN

Arnaud Devos, P. Emery, E. Defay, N. Ben Hassine, G. Parat

We present a technique based on ultrafast acoustics which permits us to measure the electrical dependence of the elastic properties of a thin piezoelectric layer. Ultrafast acoustics offers a unique way of measuring elastic properties of thin-layer in a non-destructive way using ultrashort optical...

Modelling Of Supramolecular Network Deposited On A Semiconductor Surface

Guillaume Copie, Christophe Krzeminski, Fabrizio Cleri, Younes Makoudi, B. Grandidier, Frédéric Cherioux, Frank Palmino

We investigated the self-assembly mechanisms and electronic properties of highly- symmetric organic molecules based on a substituted 1,2,5-tri(4-phenyl)benzene core[1], deposited on a passivated boron-doped Si(111)-√3x√3 R30° surface, by using ab-initio calculations, empirical molecular dynamics...

Laser ultrasonics and mode conversion for flaw depth gauging

Frédéric Faëse, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy, Mohamed Ourak

Compared to earliest non destructive testing and evaluation methods based on transducers, laser ultrasonics shows specific advantages. It is a non-contact method combining a high spatial resolution and a large bandwidth, allowing high temperature and/or geometrically complex materials testing. In...
